Mentions:
For Schiff base (SB2), the analysis of thermoanalytical curves (Figure 3) reveals a better thermal stability (up to 204 Â°C). Only the HF curve reveals an endothermic effect at 197.7 Â°C which is due to the melting and is in good agreement with the melting observed on the Boethius apparatus. TG curve indicates that a two steps degradation of this compound occurs, in 204â€“273 Â°C (with a mass loss Î”m = 44.44% and with a DTGmax = 247 Â°C), and in 273â€“357 Â°C (with a mass loss Î”m = 37.07% and with a DTGmax = 288 Â°C) temperature ranges, respectively. The HF curve indicates in these temperature ranges two maximums, at 244 and 286 Â°C which can be associated with thermooxidation processes of molecule destruction.
